... of aluminum alloy. BUE is responsible for early tool breakage due to excessive material build up from the machined part on the cutting face, leading to problems of shape irregularity and tool-tip breakage. Thus, diamond-like carbon (DLC) was deposited and tested to verify cutting precision in aluminum alloy...

... the increasing demand of more stability, more durability, and lower friction of coefficient in those extreme environments. To meet these challenges, we have applied DLC (diamond-like carbon) coatings on alumina using a PIID (plasma immersion ion deposition) technique intended for seal applications. The DLC...
